I have heard the same.  But, I can report that the bumblebees seem to think
mine are worth working. Since my trees are approx 25-30' tall (taller than
crest of house, three floors including basement, which is same level as
ground trees are on), binoculars are required to check the blooms. It looks
like there are some honeybees (and some even smaller), but the bumbles are
quite clear and are working the blooms.

I checked the hives today and there is a greenish nectar coming in
currently. I'll have to check some of my books to see if the color matches
any of the known blooms here at this time of year (tulip poplar is over,
locust is long gone, white clover may be a player, but is getting quite
scarce, elderberry nearly done, etc).  Since some neighbors have been
logging recently, I guess I can expect the drop in tulip poplar to result in
better sourwood 5 or 10 years from now.
